RESILIENT TIRE.

Specification of Letters Patent.

Patented Oct. 8, 1912.

Application filed June 23, 1911. Serial No. 636,083.

To all whom it may concern Be it known that I, CHARLES T. Senor-7N, acitizen of the United States, residing at Media, in the county ofDelaware and State of Pennsylvania, have invented a certain new anduseful Improvement in Resilient; Tires, of which the following is afull, clear, and exact description.

The object of this invention is to produce a resilient tire for thewheels of motor and other vehicles, which will be a practical andserviceable substitute for pneumatic tires, and which will not besubject to the dangers and expense of punctures, deflation and theother. vcxatious and costly objections to which pneumatic tires areexposed.

I am aware, of course, that many forms of resilient tires, other thanpneumatic, have been'devised, in which the tread sin-face or casing isof rubber or rubber compound,

comblned with metal springs, but so far as I am aware, it is originalwith me to provide such a casing with spring pockets in which metalsprings are secured, and'tho casing secured to the rim of the wheel andthe springs retained in the casing by sectional bands and clips.

Having thus stated the principle of my invention, I will proceed now toexplain the same and then will particularly point out and distinctlyclaim the part, coi'nhination or improvement which I claim as myinvention.

In the accompanying drawings illustrating the invention in theseveralfigures of which like parts are similarly designated, Figure 1 is anelevation and partial section of a wheel with my tire in place thereon.Fig. 2 is a cross-section, on a larger scale, taken on line A B, Fig. 1.Fig. 3 is a crosssection, on a larger scale, taken on line C D, Fig. 1.Fig. 4. is a side elevation, and Figs. 5 and 6 are cross-sections, onlines E F and G H, respectively, Fig. 4, of one of the sec tions of thesectional base band. Fig. 7 shows in side View, front elevation andlongitudinal section one of the clips. Fig. 8 shows in front and sideelevations the clenching band and clamp. Fig. 9 is an in side plan viewof a portion of the casing, and Fig. 10 is a side elevation of the same.

The wheel may be of ordinary construe tion and provided with a wooden orother rim, 1.

The tire comprises a casing 2, of rubber or rubber :ompound or otherresilient material or composition, such as is used for cushion orresilient as. distinguished from pneumatic tires. \Vithin this casingare molded the pockets 3, of substantially cylindrical outline andseparated from one another by intervci'iing walls 4 oi the full depthand width of the casing. Each pocket is provided with a metal cap 5fitted in a shouldered recess at the bottom of the pocket and a taperingcoiled spring 6. The easing. adjacent to the entrances to the pockets 8may be and preferably is provided with a spiral groove 7 into which theadjacent or bottom convolution of the spring is forced so as to renderthe spring stable within the pocket; and the other end convolution ofthe spring is adapted to fit tightly within the cap 5, the intermediateconvolutions of the spring being out of contact with the walls of thepocket, as clearly shown in F in.

3; In order to avoid chattering and noise in the event the spring shouldsettle or fail to fit tightly within the pocket, I provide the cap witha lining of cotton-duck, felt, or other suitable material 8, and I alsointerpose a similar lining strip 9 at the other. end of the spring.

The base band 10 of metal is placed around the casing on they inside,and this band, as shown more particularly in Fig. 4, is made up of anumber of sections and these sections are provided with cars 11 benttoward each other and adapted to fit in preformed cavities 12 made inthe sides of the casing in transverse alinement with the pockets 3,these preformed cavities being of substantially the same size as theears 1]. so

that these ears not only grasp the casing,

transversely to hold the band in place when the casing is removed fromthe rim, but also engage it longitudinally and thereby prevent motion orcreeping of the casing in both directions. The base band is made insections so as to facilitate its assembling, and more particularly tofacilitate access to the springs in case any of them become daniaged, itbeing unnecessary to remove the whole band in order to gain access toany particular spring. The casing thus equipped with springs and basebands is applied to the rim 1 of the wheel and secured thereto by meansof the sectional bands 13, which, as shown in Figs. 2, 3 and 8, have theflanged edges 14,- whieh enter grooves 15 in the sides of the casing;and these sections have at adjacent ends the clamping brackets 16riveted or otherwise securely fastened to them and connected by bolts17, so that the sections may be drawn tightly together. These bandsections are provided at intervals with slots 18 and these slots areengaged by clips 19 which are secured to the rim by bolts 20. Lips 21 onthese clips 19 enter the slots 18 in the band sections in order to holdthem .in place and also to hold them against longitudinal movement.

The walls 4 have embedded in them transversely at their inner edges,metal rods or bars 22 which serve to reinforce these walls and preventthem from puckering where they engage the base band 10. p I

As shown more particularly in Figs. 1, 2 and 3, the rim 1 of the wheelis made of wood and preferably has a metal tire 23 surrounding it, andthe resilient tire is placed upon this metal tire instead of directlyupon the wooden rim; alt-houghthe invention is not limited to the use ofany particular con-.

struction of wheel rim.

The springs are designed to practically fill the pockets so as tosupportthe casing both transversely and longitudinally, and

the invention is not limited to the employ-- ment of tapered springs,although .preferonce is had for tapered springs, especially as thecommon practice is to make the ordinary cushion or solid tire taperingin crosssection.

By the construction described, allowance is made for variations in therim of the wheel, and it is possible to compensate for such variationsin wear,

It is to be understood that while I have herein shown and described thebest mode in which I have contemplated applying the principle of myinvention, I wish not to be understood as limiting my invention or theclaims therefor herein made tomere details of construction andarrangement, since these may be varied to suit the conditions underwhich the invention is used.

What I claim is 1. A resilient tire for vehicle wheels, having aresilient casing provided with integral individual open-endedcylindrical I pockets having grooves in their walls adjacent to the openends thereof, a tapering coil spring arranged in eachof said pockets andhaving its smaller end engaging the bottom of the pocket and its largerterminal convolution engaging the groove at the opening in the pocket,and a band applied to the casing and covering said-openings to hold thesprings in place and adapt the casing for the application to a wheel.

2. A resilient tire for vehicle Wheels, having a resilient casingprovided with integral individual cylindrical pockets having ashouldered recess in their bottoms and a groove in their walls adjacentto the entrances thereto, a tapering coiled spring arranged in each ofsaid pockets having its smaller end fitted in the shouldered recess atthe bottom of its pocket and its larger, end engaging the groove at theentrance to the pocket, and a band applied to the casing i0 to hold thesprings in place and adapt the 1 casing for the application to a wheel.9 3. A resilient tire for vehicle wheels, having a casin provided withintegral individual cylind ical pockets having a reduced portion intheir bottoms and grooves in their walls adjacent to the entrancesthereto, a tapering coiled spring arranged in each of said pocketshaving its smaller end fitted in the reduced portion at the bottom ofits pocket and its larger end engaging the groove at the entrance to thepocket, and its intermediate convolutions out of contact with the wallsof the pocket, and a band 7 applied to the casing to hold the'springs in5 place and adapt the casing for. application to a wheel. y

4. A resilient tire for vehicle wheels, having a casing provided withpockets, coiled y springs mounted in said pockets, a sectional metallicbase band applied to and carriedbg-7- fl, I

the casing for covering .said pockets an holding said springs in placewhen the cas-g ing is removed-from the wheel, spaced ears; on said baseband, and spaced cavities in the sides of the casing in transversealinement with'the pockets to receive said ears to hold the sections ofsaid band in place 1 upon the casing and prevent creeping of the casing,and means for. fastening the tire to- .100 v the rim of a wheel. 7

In testimony whereof'I have hereunto set my hand this 28th day of June,A. 1)., 1911. w
